DETAILED DESCRIPTION OF THE EMBODIMENTS

To make the objectives, technical solutions, and advantages of the present invention clearer, the following describes the embodiments of the present invention in detail below with reference to the accompanying drawings.

Embodiment 1

The first embodiment of the present invention provides a method for intelligent categorization of bookmarks, the procedure of which is as shown in FIG. 1, including:

Step 101: acquiring a bookmark link address requested for categorization by a client;

Step 102: categorizing the bookmark link address requested for categorization; and

Step 103: returning a categorization result as a bookmark category to the client.

In this embodiment, by acquiring a bookmark link address requested for categorization by a client, categorizing the bookmark link address requested for categorization, and returning a categorization result as a bookmark category to the client, the objective of intelligent categorization of the bookmarks is achieved so that time consumption caused by users' manual organization and categorization of the bookmarks is avoided. In addition, a better user experience on the browser is brought to users.

Embodiment 2

The second embodiment of the present invention serves as an improvement of the first embodiment, the procedure of which is as shown in FIG. 2, including the following steps:

Step 201: A categorizing server acquires a bookmark link address requested for categorization by a client.

Specifically, when a user uses a browser to collect and store Web pages, the browser sends bookmark link addresses of the Web pages to a server, and the bookmarks are automatically categorized by using powerful calculation capabilities of the server.

The categorizing server is a server for intelligently categorizing the bookmarks.

Step 202: The categorizing server presets at least one network address category, and sets at least one keyword or/and one link address corresponding to the network address category, where the preset link addresses constitute a link library.

Specifically, a plurality of network address categories, for example, science and technology, education, entertainment, blog, and the like, are preset. In addition, keywords or/and link addresses corresponding to the network address categories are set, where the preset link addresses constitute a link library.

Further, in the area of current natural language processing, a vector space model is mainly used for expressions of text. Since it is improper to directly process the original form of natural language using mathematical method, therefore, automatic processing of the natural language is hard to implement. The essence of the vector space model is to describe a document using vectors, for example (W₁, W₂, W₃, . . . , W_(m)), where W_(m) is the weight of the m^(th) feature item. The feature item may be a term or phrase. Generally, it is preferable to use a term as the feature item, instead of using a phrase. Therefore, the selected feature items are used as each vector of the vector space. The feature items are used as dimensions of the vectors to represent a document, and term frequency is used to represent a vector component corresponding to the feature item. The method for calculating a term frequency is mainly based on the following TF-IDF formula:

${W\left( {t,d} \right)} = \frac{{{tf}\left( {t,d} \right)} \times {\log \left( {{N/n_{i}} + 0.01} \right)}}{\sqrt{\sum\limits_{i = 1}^{m}\left\lbrack {{{tf}\left( {t,d} \right)} \times {\log \left( {{N/n_{i}} + 0.01} \right)}} \right\rbrack^{2}}}$

W (t, d) is the weight of term t in document d; tf (t, d) is the term frequency of term t in document d; N is the total number of training documents; n, is the number of documents where term t is present in the training document set, where i=1, 2, . . . , m (m is the number of terms); and the denominator of the formula is a normalization factor. TF-IDF is a commonly used weighting technology for information search and information exploration, and is widely used in information search, document categorization, and other related fields, for evaluating importance of a word in a document of a document set or a text corpus. The importance of a word proportionally increases with increase of the frequency of the word in a document, and meanwhile proportionally decreases with increase of the frequency of the word in a text corpus. The more frequently a term is present in a document, the stronger the capability of the term for distinguishing document attribute, and the greater the weight value.

Further, the weight of each keyword corresponding to each preset network address category is calculated by using the TF-IDF formula. The weights of all terms in the same term library are combined to form an N-dimensional vector, where N represents the number of keywords in the term library. The N-dimensional vector can be represented as (weight of term 1, weight of term 2, weight of term 3, weight of term 4, . . . , and weight of term N). The weight of each keyword forms the vector of preset network address category, for calculating similarity with the bookmark of the Webpage collected by the user.

Step 203: The categorizing server categorizes the bookmark link address requested for categorization.

Specifically, after a server side receives the bookmark link addresses requested for categorization from the client, a load balancing server assigns the bookmark link addresses to different categorizing servers for categorization.

Further, according to this embodiment, the bookmark is categorized in three manners. The first manner is to perform matching in the link library for the bookmark. The second manner is to perform a similarity comparison between the vector space model and the keyword of the preset category to obtain a categorization result, if the matching fails. The third manner is to directly perform a similarity comparison between the vector space model and the keyword of the preset category to obtain a categorization result, instead of performing link matching. Therefore, step 203 may specifically include:

Step 2031: A load balancing server is employed to share the workload of the categorizing servers.

Specifically, the server side employs a load balancing server before a categorizing server cluster to balance the workload of the categorizing servers. The load balancing server is specifically configured to receive the bookmark link addresses requested for categorization from the client, then distribute the link addresses in the categorizing server cluster according to a configured balancing policy, and maintain availability of the server.

Step 2032: The categorizing server performs link address matching in the link library for the bookmark link address requested for categorization.

Specifically, after receiving the bookmark link address requested for categorization assigned by the load balancing server the categorizing server, the categorizing server firstly performs domain name matching in the link library for the link address. A domain name is the name of a computer or a computer group on the network, consisting of a string of characters spaced by a dot.

Step 2033: If a link address in the link library matches the bookmark link address requested for categorization, the categorizing server uses the network address category corresponding to the matched link address as the categorization result.

Specifically, the majority of known domain names can be found by performing domain name matching, and the network address category corresponding to the matched link address is used as the categorization result. Step 204 is performed to return the categorization result to the client.

For example, the domain name of a bookmark link address stored by the user is cnbeta.com, cnbeta.com is recorded in the link library in advance, and the domain name is categorized into the category of science and technology news. After receiving the request from the client, the server side performs matching in the link library and obtains the domain name, and finds that the network address category corresponding to the domain name is science and technology news, and returns the category to the client.

Further, if no link address in the link library matches the bookmark link address stored by the user, step 2034 is performed.

Step 2034: If no link address in the link library matches the bookmark link address requested for categorization, the categorizing server extracts key information from the Web page corresponding to the bookmark link address requested for categorization, and performs word segmentation for the key information to generate a keyword.

Therefore, step 2034 may specifically include:

Step 20341: extracting key information of the Web page corresponding to the bookmark address.

Specifically, if no link address in the link library matches the bookmark link address stored by the user, this means that the categorizing server does not record the link address and cannot judge, according to known information, which type the Web site belongs to. In this case, the categorizing server analyzes the Web page corresponding to the link address to judge the type of the Web site.

Further, the categorizing server accesses the link address, extracts key information of the Web page, finds the title, keyword, and specific content on the Web page, and analyzes the information. The method for extracting Web page information belongs to the prior art, which is not limited in the embodiments of the present invention.

Step 20342: performing word segmentation for the key information to generate a keyword.

Specifically, word segmentation is performed for the extracted key information to generate a keyword. Word segmentation is a process of combining consecutive character sequences into a new word sequence according to a specific rule. The categorizing server analyzes the category of the segmented word. The method for segmenting Chinese words belongs to the prior art, which is not limited in the embodiments of the present invention.

Step 20343: calculating a vector of the generated keyword.

Specifically, the weight of each term in the keyword is calculated using the TF-IDF formula in step 202 to obtain a vector of the generated keyword (weight of term 1, weight of term 2, weight of term 3, weight of term 4, . . . , weight of term N).

Step 2035: The categorizing server performs a similarity comparison between the generated keyword and the preset keyword corresponding to each network address category, and uses the network category corresponding to the preset keyword with the largest similarity as the categorization result.

Specifically, the computer is used to automatically categorize objects such as files and documents, which typically includes automatic aggregation and automatic categorization. The automatic aggregation differs from the automatic categorization in that: in the automatic aggregation, it is not necessary to define a categorization system in advance and calculating similarity, and the server does not need to collect a feature term library and link addresses for categorization in advance, which, as a result, results in a poorer effect than the automatic categorization. With regard to the automatic categorization, a predetermined categorization system is required, and a batch of pre-categorized objects is needed for each category as a training document set. During actual categorization, one or multiple categories are determined, according to the acquired categorization knowledge, for the documents to be categorized.

In the embodiments of the present invention, the automatic categorization method is used to calculate, by using the document vector space model, the key information of the Web page after extraction and word segmentation, and determine the category of the document. Before calculation for categorization, the categorization system is predetermined, and a corresponding term library is provided for each category as a training document set. Categorization of a text/document is performed under a specific categorization system, and the associated category of text/document is automatically determined according to the content of the text/document. From the aspect of mathematics, text/document categorization is a mapping process, where a text/document with no specified category is mapped to a known category.

Further, a similarity calculation is performed between the vector of the generated keyword and the vectors of all network address categories, and all similarity values obtained are sequenced in descending order. Therefore, it can be determined that the Web page corresponding to the bookmark link address belongs to the network address category corresponding to the maximum similarity.

The calculated similarity between two documents is represented by a cosine value of the angle formed by the corresponding vectors, and the calculation formula is as follows:

${{Sim}\left( {d_{i},d_{j}} \right)} = {{\cos \; \theta} = \frac{\sum\limits_{k = 1}^{n}{w_{ik} \times w_{jk}}}{\sqrt{\left( {\sum\limits_{k = 1}^{n}w_{ik}^{2}} \right)\left( {\sum\limits_{k = 1}^{n}w_{jk}^{2}} \right)}}}$

W_(ik) and W_(jk) represent weight values of the K^(th) features in documents d_(i) and d_(j) respectively, and Sim(d_(i),d_(j)) represents the similarity between document d_(i) and document d_(j).

Assuredly, similarity comparison is merely one way of determining the category. The category may also be determined in other ways, which is not limited in the embodiments of the present invention.

Step 2036: The categorizing server extracts key information from the Web page corresponding to the bookmark link address requested for categorization, and performs word segmentation for the key information to generate a keyword.

Specifically, during the process of categorizing the bookmark link address requested for categorization, matching in the link library may not be performed, and similarity calculation is directly performed instead. Therefore, step 2036 may specifically include:

Step 20361: extracting key information of the Web page corresponding to the bookmark address;

Step 20362: performing word segmentation for the key information to generate a keyword; and

Step 20363: calculating a vector of the generated keyword.

Further, step 2036 shares the same concept and principle with step 2034, which is not detailed herein any further.

Step 2037: The categorizing server performs a similarity comparison between the generated keyword and the preset keyword corresponding to each network address category, and uses the network category corresponding to the preset keyword with the largest similarity as the categorization result.

Further, step 2037 shares the same concept and principle with step 2035, which is not detailed herein any further.

Step 2038: If no preset network address category matches the bookmark link address requested for categorization, the categorizing server uses a default category as the categorization result.

Specifically, if no result is obtained after the categorizing server performs matching in the link library, and similarity calculation for the bookmark link address, the category of the bookmark is categorized into the default category and returned to the client.

Step 204: The categorizing server returns a categorization result as a bookmark category to the client.

Specifically, in the above process, matching is performed in the link library for the bookmark link address and/or document similarity is calculated for the bookmark link address, and the categorization result is returned to the client.

By the matching and calculation performed by the categorizing server, the category of the bookmark link address is obtained, and the category is returned to the load balancing server, and the load balancing server returns the category to the browser of the client. After receiving the category of the bookmark link address, the browser automatically organizes and places the bookmark to the folder of the category according to the received category, thereby completing intelligent organization and categorization of the bookmarks of the user.

Specifically, if no result is obtained after the categorizing server performs matching in the link library and similarity calculation for the bookmark link address, the category of the bookmark is categorized into the default category and returned to the client. The client places such uncategorized bookmark under the default category directory.

In this embodiment, by acquiring a bookmark link address requested for categorization, categorizing the bookmark link address requested for categorization, and returning a categorization result as a bookmark category to the client, the objective of intelligent categorization of the bookmarks is achieved. In addition, for a bookmark link address not matched successfully in a preset link library, by extracting key information of the Web page corresponding to the bookmark link address, performing word segmentation for the key information, and performing a similarity calculation for the keyword and the keyword corresponding to the preset network address category, a corresponding category with the greatest similarity is obtained and used as the category of the bookmark link address. In this way, time consumption caused by users' manual organization and categorization of the bookmarks is avoided. In addition, a better user experience on the browser is brought to users.
